2-Decarboxy-2-hydroxymethyl-5-oxa-11-deoxy-PGE1 compounds

ABSTRACT

This invention comprises certain analogs of the prostaglandins in which the C-1 carboxyl is replaced by a primary alcohol. Also provided in this invention, are novel chemical processes useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmocological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

The present application is a divisional application of Ser. No. 647,363, filed Jan. 8, 1976, now issued as U.S. Pat. No. 4,028,419.

The present invention relates to prostaglandin analogs for which the essential material constituting a disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,028,419.
